    Journal: Zh Evol Biokhim Fiziol; 2011; 47(3):212-8. PubMed ID: 21780640.
    Abstract:
    Activity and properties of fructose bisphosphatase (FBPase) was studied in the free-living turbellarian Phagocata sibirica. All subcellular fractions of P. sibirica (12 000 g cytosol, 105 000 g cytosol, mitochondria, and microsomes) have the FBPase activity. There was studied dependence of the FBPase reaction rate on the substrate concentration. For realization of the enzyme activity, the high affinity to substrate and presence of bivalent cations (Mg2+ or Mn2+) are necessary. The was studied the effect of various effectors as well as of monovalent (Na+, K+, Li+, and NH4+) and bivalent (Zn2+ and Cu2+) cations.
